In one embodiment of the present of invention, motor rated power 1kw, the safety coupling uses stainless steel (steel density
Take 7900kg/m3) manufacture, 235 design volume of spacer pin is 1.96x10-5m3, weight 0.155kg, radius 0.05m, following table
For coefficient of friction table, it is known that steel-steel coefficient of friction is 0.15.
When motor speed rises to 1500r/min, can calculate Motor torque T is 6.36MN, and arm of force M is
0.025m then calculates torsion FnFor 254.6N, the frictional force generated at this time by torsion: F1=μ Fn=0.15 × 254.6=
38.19N
233 elastic force of spring is 30N at this time, and rule of thumb taking normal pressure is 100N, the frictional force that spring 233 generates at this time
Are as follows: F2=μ FN=0.15 × 100=15N
Calculating centrifugal force f suffered by spacer pin 235 as shaft coupling parameter is 191N, is always rubbed suffered by spacer pin 235 at this time
Power are as follows: F=F1+F2=38.19+15=53.19N
Since 235 friction F of spacer pin is much smaller than centrifugal force f, then know to rise to 1500 r/ when motor speed
When min, which must no longer be interlocked, and can avoid the excessive damage load of motor speed.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
